Drivers: hv: util: Fix a bug in the KVP code
Add code to poll the channel since we process only one message at a time and the host may not interrupt us. Also increase the receive buffer size since some KVP messages are close to 8K bytes in size. Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Cc: <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
